Smitten Kitchen has the recipe and a photo was on the Martha Stewart show (I'm soooo bummed I forgot to set my DVR for her show on bloggers!)

You know this cake is serious when you see how much batter it makes! I swear that could make 36 cupcakes...so be sure to slice this cake thin, thin! This makes three 8" layers.

The frosting is a delicious combination of cream cheese, butter, 5 cups of powdered sugar (I used 4 cups) and smooth peanut butter. After a chill, a ganache of chocolate, peanut butter and half and half is poured over the top of the cake.

The cake is seriously moist and decadent. Smitten Kitchen calls it intense and I completely agree!

Making this cake could actually make you lose weight! Really.See, the cake is sooo heavy. Like 15 pounds of cake heavy. If you just carry it around with you, you'll totally burn calories. I practically worked up a sweat bringing it into work! (And if you are planning to travel with it, you might want to throw in some dowels to keep it all together).

Three for three!

So far, I've made the Chai cake and Strawberry shortcake from Alisa's book...next up, the Ginger Mango Lime Curd cake.

I made this cake for my daughter's birthday after seeing the recipe on Smitten Kitchen. We were feeding off of it for a week, it's so big and rich! One thing, did you use up all of the chocolate ganache frosting? I used about 80 percent of it, and it still ended up covering the entire cake (couldn't even see the pb frosting underneath). I didn't realize it was going to run so far down the sides of the cake.

Leah, I definitely didn't use all the ganache. I think I used about 60% - I have to note in the book saying, "cut in half" for the next round! :) I brought my cake in for my co-workers so I wouldn't have it in the house for days. Man, this cake is RICH! :)

Can that cake be any more decadent!?! My mouth was watering just looking at all those wonderful pictures. I almost didn't want to look away! Would you say that it's the best chocolate cake you've ever had?

I'm always looking for better recipes. The only chocolate cake recipes I've made are epicurious's double chocolate cake and dorie's devils food white out. How does this cake compare with other ones you've made in flavour, texture and overall.

Well, I came to see if you had the plum cake up yet, and this is what I found. Amazing layer cake goodness. I will need to find an excuse to bake this. Must be the third anniversary of something in my life! Congrats to you, btw. Way to pursue your interests!Nancy
